Cory Bohon has a nice little tip over at TUAW about this one fellow you must be pretty familiar with, the Inspector. This little tabbed window is a common feature in several Mac OS X applications and provides access to a lot of frequently used features. But, of course, you knew that.
What you might not have known, however, is that you can have more than a single Inspector window any time you want. Generally, you switch between various modes of the Inspector using the tabs at the top. But if you’re not a great fan of having to switch back and forth between the different modes and have ample screen space to waste utilize, you can just hold down the Option key before hitting one of the tabs.
What happens next? Just try it out yourself; I won’t spoil the suspense.
